- The graph for my sleep time at first showed rem but the last few nights it showed no rem sleep although I know I dreamed.
I downgraded to previous Android app version (4.32) on August 6 and my REM appeared again on sleep graphs after two nights had passed. REM also appeared on past sleep graphs between July 29 and August 5, that didn't show REM in the first place - when I was using the 4.33 app version.
The version of the watch software has been the same during all this time.
